Sarcophagus of the Twelve Apostles, dating from the 5th century. The lid is decorated with three monograms made of Xs laid across Greek crosses (+), with reliefs of birds, vines and crosses on the ends. On the main panel of the sarcophagus, Christ sits enthroned in the center and gives Paul the scroll of the Law. On his other side, Peter approaches, carrying a tall cross and his keys. Other apostles hold crowns or raise a hand in prayer.
